Today, Good Morning America hosted PEN/Hemingway Award winner Justin Cronin, whose The Passage (Ballantine, 978-0345504968, $27; RH Audio abridged CD, $45) pubs today. PW’s starred review called it an “engrossingly horrific account of a post-apocalyptic America overrun by the gruesome reality behind the wish-fulfillment fantasies.”

On Today, Jim Cole described Blindsided: Surviving a Grizzly Attack and Still Loving the Great Bear (St. Martin's Press, 978-0312601096, $25.99), which also pubs today.

This evening, the ABC Family channel premieres the series Pretty Little Liars, based on the Sara Shepard book (HarperTeen, 978-0062009548, $8.99), whose reprint/TV tie-in edition pubs today.

The Leonard Lopate Show chatted with Lydia Davis, whose latest is The Collected Stories of Lydia Davis (FS&G, 978-0374270605, $30).

The Colbert Report meets with Make magazine editor Mark Frauenfelder, author of Made by Hand: Searching for Meaning in a Throwaway World (Portfolio, 978-1591843320 $25.95; Tantor unabridged CD, $29.99). PW thought “People have hobbies because they are interesting and fun; by inflating hobbyism into a belief system, Frauenfelder doesn't add much to their appeal.”
